Raeti

The Raeti were a confederation of Celts that inhabited central Switzerland, the Austrian region of Tyrol, and some parts of northern Italy.

History
The Raeti tribe were located to the north of the Alps mountains, which separated them from the Roman Republic of Italy to the south. The Raeti tribe signed a non-aggression pact with Roman dictator Octavian in 42 BC, ensuring that they would not be conquered by the Romans; Octavian was preoccupied with the War of the Second Triumvirate and could not spare the troops to fight them on any occasion.
